They can still do a lot. I'd much rather use software I can inspect to talk to the services I really need (firebase push) and replace the ones I can (like location). MicroG is great for that <3
It can even fake some of the more basic safetynet attestation crap and during Covid they made their own version of the Bluetooth thing. Marvin the dev is a great guy.
I don't know why people hate on MicroG so much. Grapheneos devs foam at the mouth when you mention it and in the lineageos irc channel you get Insta kicked when you mention it.
